Maybe you are now asking for this two green boxes. Only one dynamic tiering license is allowed per SAP HANA system. Failover nodes mount the storage as part of the failover process. Dynamic tiering enhances SAP HANA with large volume, warm data management capability. Network for internal SAP HANA communication: 192.168.1. To set it up is one task, to maintain and operate it another. redirection. SAP Host Agent must be able to write to the operations.d
* as internal network as described below picture. The BACKINT interface is available with SAP HANA dynamic tiering. Only set this to true if you have configured all resources with SSL. system. # 2021/04/26 added PIN/passphrase option for sapgenpse seclogin Not sure up to which revision the "legacy" properties will work. You just have to set the dbs/hdb/connect_property parameter to the correct value: In some cases, you may receive an error if you force the use of TLS/SSL: You have to set some tricky parameter due to the default gateway of the Linux server. Disables the preload of column table main parts. Please refer to your browser's Help pages for instructions. After a validation on the non prod systems the change was made on our Production landscape that is using the HANA System Replication (HSR) Both SAP HANA and dynamic tiering hosts, including standby hosts, use storage APIs to access the devices. global.ini -> [communication] -> listeninterface : .global or .internal There are two types of network used in HANA environment: Since we have a distributed scenario here, configuration of internal network becomes mandatory for better system performance and security. A shared file system (for example, /HANA/shared) is required for installation. Copyright |
if no mappings specified(Default), the default network route is used for system replication communication. It would be difficult to share the single network for system replication. Replication, Register Secondary Tier for System

Internal communication channel configurations(Scale-out & System Replication). Enables a site to serve as a system replication source site. For sure authorizations are also an important part but not in the context of this blog and far away from my expertise. Chat Offline. Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. # 2021/04/06 Inserted possibility for multiple SAN in one request / certificate with sapgenpse It differs for nearly each component which makes it pretty hard for an administrator. The cleanest way is the Golden middle option 2. Extended tables behave like all other SAP HANA tables, but their data resides in the disk-based extended store. There can be only one dynamic tiering worker host for theesserver process. If there are multiple dynamic tiering hosts available and you do not specify a host or port, the SAP HANA system randomly selects from the available hosts. You have installed and configured two identical, independently-operational. You comply all prerequisites for SAP HANA system

instances. If set on the primary system, the loaded table information is
the global.ini file is set to normal for both systems. Stay healthy, In a traditional, bare-metal setup, these different network zones are set up by having * sl -- serial line IP (slip) Setting Up System Replication You set up system replication between identical SAP HANA systems. Updated the listeninterface and internal_hostname_resolution parameters for the respective TIER as they are unique for every landscape (check SAP note 2834711). Therefore, you are required to have 2 separate networks for system replication, one is for primary site to secondary site and another is for secondary site to tertiary site and each host in your secondary site should have an additional NIC. own security group (not shown) to secure client traffic from inter-node communication. Perform SAP HANA
Please note that SAP HANA Dynamic Tiering ("DT") is in maintenance only mode and is not recommended for new implementations. can use elastic network interfaces combined with security groups to achieve this network Understood More Information instances. This is the preferred method to secure the system as it's done automatically and the certificates are renewed when necessary. Please use part one for the knowledge basics. We know for step(4), there could be one more takeover, and then site1 will become new primary, but since site1 and site2 has the same capacity, it's not necessary to introduce one more short downtime for production, right? Because site1 and site2 usually resides in the same data center but site3 is located very far in another data center. Another thing is the maintainability of the certificates. Each tenant requires a dedicated dynamic tiering host. (1) site1 is broken and needs repair; I have not come across much documentation on this topic and not sure if any customer experienced such a behavior so put up a post to describe the scenario configure security groups, see the AWS documentation. groups. Here your should consider a standard automatism. of the same security group that controls inbound and outbound network traffic for the client Or see our complete list of local country numbers. Download the relevant compatible Dynamic Tiering software from SAP Marketplace and extract it to a directory. But the, SAP app server on same machine, tries to connect to mapped external hostname and if tails of course. How you can secure your system with less effort? The additional process hdbesserver can be seen which confirms that Dynamic-Tiering worker has been successfully installed. An optional add-on to the SAP HANA database for managing less frequently accessed warm data. These are called EBS-optimized path for the system replication. external(public) network: Channels used for external access to SAP HANA functionality by end-user clients, administration clients, application servers, and for data provisioning via SQL or HTTP, internal network: Channels used for SAP HANA internal communication within the database or, in a distributed scenario, for communication between hosts. As promised here is the second part (practical one) of the series about the secure network communication. Use Secure Shell (SSH) to connect to your EC2 instance at the OS level. When set, a diamond appears in the database column. We used NFS storage in our case which has following requirement: The actual architecture that we followed is as follows: Dedicated host deployment with /hana/shared/ mounted on both the hosts. General Prerequisites for Configuring SAP
Unregisters a secondary tier from system replication. To change the TLS version and the ciphers for the XSA you have to edit the xscontroller.ini. The latest release version of DT is SAP HANA 2.0 SP05. IMPORTANT : the parameters in the global.ini must be set prior to registering the secondary system which means that you need to un-register and re-register if you want to change the configurations.
